Hey all,
Has anyone heard of CBO bugs on tables with 0 rows or a low row count
(<6)? Appparently sub-optimal plans were generated causing performance
issues. The solution was to delete statistics on those tables. I was
kind of surprised when I heard this so I searched on Metalink and can't
find anything.
Thanks
